I love it. Ofc it‘s unclear if and how this can be enforced, but we MUST find a proper solution to this problem. It also extends to images and videos. ML should not become an escape hatch for copyright evasion. We invented copyright for a reason - without it, our capitalistic system is flawed and unfair. Not in a sense that it‘s not „nice“: each system has its stress limits, and if we bias the odds continuously in favor of few, we risk instability.

Of course it can be enforced. If you're not compliant with the terms of a license you don't have a license and are a pirate. If the license is nonsensical then no one can run the software.

No, there is no reason to believe it can be enforced.

In the US, training is considered fair use at this time, and thus DOES NOT require a license at all. That might change, but I doubt it.
